Sometimes you just need to hear a song right this second and you don't want to futz about hunting it down on Google. TuneCrawl is a web app that searches songs on Spotify, YouTube, and Soundcloud so you get to listening right away.

TuneCrawl is great for those "I need to listen to that song now," moments because it's fast and only shows you songs that are actually playable. When you get the results, you can click the play button and it'll play right there in your browser. No messing around with Wikipedia entries, blog posts, or anything else. It should come in handy when you really need to get that horrible song out of your head.
